2.9.1 Workpiece Process Result
Overview
Using the workpiece process result requires that the NC inform i CELL
of the beginning and end of the process, and, if necessary, the
workpiece ID and process end ID. This information transfer between
the NC and i CELL is performed using the custom macro variables of
the NC.
The NC changes the values of custom macro variables that mean the
beginning and end of the process, using an NC program. i CELL reads
these values periodically to judge on the beginning and end of the NC
process, and records the result in a database.

Accordingly, the following procedure is needed to set up the workpiece
process result.
<1> Determine what items are to be acquired from the NC.
<2> Determine to which custom macro variables the items to be
acquired are to be assigned.
Items to be acquired from the NC
i CELL collects the following required and optional items from the NC,
using the Workpiece Process Result tab.
Required items
Sequence Number, Process Begin, Process End,
Handshake ON/OFF
Optional items
